BACKGROUND OF THE INVENTION
[0003] For the demand of electricity, some vehicles are equipped
with conventional power generating devices, such as solar panels or
wind power generating devices thereon. The solar panels on the
vehicles are unable to generate electricity during cloudy or rainy
days. Similarly, when a vehicle equipped with the conventional wind
power generating device is stopped, a fan blade of the wind power
generating device is stopped accordingly and unable to generate
electricity due to the lack of wind force.
[0004] However, there is still a need for electricity even when
vehicles are stopped for a moment such as waiting for the red
light. In other words, the conventional wind power generating
device is not suitable for the condition in practice of the
vehicle. Thereby, it is necessary to propose a wind power
generating device suitable for the transportation vehicles.
SUMMARY OF THE INVENTION
[0005] Therefore, an objective of the present invention is to
provide a wind power generating device installed in a vehicle
capable of maintaining a time period of electricity generation even
when wind speed is low or none due to vehicle stop

peripheral of the securing ring and facing the rotating disk in
such a manner that the corresponding magnetic element is with
magnetic repulsion to the magnetic element such that a magnetic
repelling force between the magnetic elements and the corresponding
magnetic elements is generated; and a power generating device
having a power input shaft, the power input shaft being kinetically
connected to the shaft connecting portion so as to rotate with the
rotating disk.
[0007] In one embodiment of the present invention, each ball
chamber is provided with one ball.
[0008] In one embodiment of the present invention, the deviating
angle is 45 degree.
[0009] In one embodiment of the present invention, the wall
shifting angle is 45 degree.
[0010] In one embodiment of the present invention, each magnetic
element and each corresponding magnetic element face each other

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] The preferred embodiments of the present invention are
described in detail below with reference to FIG. 1 to FIG. 4. The
description is used for explaining the embodiments of the present
invention only, but not for limiting the scope of the claims.
[0021] As shown in FIG. 1 to FIG. 4, in one embodiment of the
present invention, a wind power generating device 100, comprises: a
fan blade 1 being rotated when receiving a wind force, a rotating
device 2 including a rotating disk 20, a plurality of magnetic
elements 21, a plurality of ball chambers 22 and a plurality of
balls 23, the rotating disk 20 having a shaft connecting portion
201, the shaft connecting portion 201 being coaxial with the
rotating disk 20, the rotating disk 20 kinetically connected to the

the rotating disk 20, the plurality of ball chambers 22 being
annularly arranged by surrounding the shaft connecting portion 201,
each ball chamber 22 extending outward from an outer wall 202 of
the shaft connecting portion 201, each ball chamber 22 being formed
with two side walls 221, each side wall 221 being allocated as
being shifted with a wall shifting angle .theta.2 from the radial
direction of the rotating disk 20, and each ball chamber 22 being
provided with at least one ball; a securing ring 3 neighbored and
surrounding the rotating disk 20, the securing ring 3 including a
plurality of corresponding magnetic elements 31, each corresponding
magnetic element 31 being configured as annularly arranging in
inner peripheral of the securing ring 3 and facing the rotating
disk 20 in such a manner that the corresponding magnetic element 31
is with magnetic repulsion to the magnetic element 21 such that a
magnetic repelling force between the magnetic elements 21 and the
corresponding magnetic elements 31 is generated; and a power
generating device 4 having a power input shaft 41, the power input
shaft 41 being kinetically connected to the shaft connecting
portion 201 so as to rotate with the rotating disk 20.
[0022] As shown in FIG. 1, the wind power generating device 100
according to the embodiment of the present invention is configured
to enable the fan blade 1, the rotating device 2, and the power
input shaft 41 of the power generating device 4 to share a common
transmission shaft for rotation. In other embodiments, a
transmission element, such as a reduction drive or a coupling, is
used to transfer kinetic energy between the fan blade 1 and the
shaft connecting portion 201, and/or between the shaft connecting
portion 201 and the power input shaft 41 of the power generating
device 4.
[0023] As shown in FIG. 2, in one embodiment of the present
invention, the wind power generating device 100 is provided with
the fan blade 1 including a center shaft 11 and a plurality of
blades 12. The center shaft 11 includes a shaft body 111 and a cone
portion 112 projecting forward and tapering from the shaft body
111. The plurality of blades 12 is allocated around the shaft body
111. An apex angle .theta.3 of the cone portion 112 is less than 30
degrees. By means of the low resistance provided by streamlined
outline of the cone portion 112, kinetic energy of the wind can be
better transferred to the blades 12 to reduce energy loss.
[0024] As shown in FIG. 2 and FIG. 3, each blade 12 includes a
front edge 121, a rear edge 122 and an inner edge 123. The inner
edge 123 is connected between the front edge 121 and the rear edge
122. An outer edge portion of the front edge 121 and an outer edge
portion of the rear edge 122 are in curve shape. Further, a curving
degree of each rear edge 122 is larger than a curving degree of
each front edge 121. A front end 123a of the inner edge 123 is
connected to the front portion of the shaft body 111 while a rear
end 123b of the inner edge 123 is connected to the rear portion of
the shaft body 111. A middle end 123c is a middle portion of the
inner edge 123 located between the front end 123a and the rear end
123b. The middle end 123c is in a U-shape and extends outward along
the radial direction of the shaft body 111 such that a wind-guiding
hole h is formed between the inner edge 123 and the shaft body 111
in such a manner that the blade 12 is formed as a three-dimensional
U-shape bending from front side to rear side. A three-dimensional
configuration of the wind-guiding hole h and the blade 12 enables
the fan blade 1 to have good wind load capacity.
[0025] The periphery of the rotating disk 20 is provided with a
plurality of slots, each slot being arranged in equidistance to
accommodate the magnetic elements 21. The inner edge of the
securing ring 3 is also provided with a plurality of slots arranged
in equidistance to accommodate the corresponding magnetic elements
31. The magnetic elements 21 and the corresponding magnetic
elements 31 are permanent magnets. Each magnetic element 21 is
allocated in a magnetic moment direction that shifts in the same
clockwise or same counterclockwise direction with a deviating angle
.theta.1 from a radial direction of the rotating disk 2. In the
present embodiment, the deviating angle .theta.1 is 45 degrees. Of
course, the deviating angle .theta.1 may also be other non-zero and
non-vertical degree.
[0026] As shown in FIG. 4, in the present embodiment, each magnetic
element 21 is allocated in the magnetic moment direction parallel
to the longitudinal direction of each magnetic element 21. Further,
an outward side of each magnetic element 21 is a south pole. Each
corresponding magnetic element 31 is allocated in the magnetic
moment direction parallel to the longitudinal direction of each
corresponding magnetic element 31. Further, an inward side of each
corresponding magnetic moment 31 is a south pole. Accordingly, each
magnetic element 21 and each corresponding magnetic element 31 face
each other with the same polarity. A magnetic force induced between
each magnetic component 21 and each corresponding magnetic
component 31 generates a torque. In other embodiments, each
magnetic element 21 and each corresponding magnetic element 31 face
each other with the opposite ones of polarity such that the
magnetic force induced between each magnetic element 21 and each
corresponding magnetic element 31 generates a reverse torque.
[0027] As shown in FIG. 4, the side wall 221 of each ball chamber
22 is a flat plane that shifts in the same clockwise or same
counterclockwise direction with a wall shifting angle .theta.2 from
a radial direction of the rotating disk 20. In the present
embodiment, the wall shifting angle .theta.2 is 45 degrees. Of
course, the wall shifting angle .theta.2 may also be other non-zero
and non-vertical degree.
[0028] In the present embodiment, each ball chamber 22 is provided
with one round ball 23. When the rotating disk 20 is rotating, a
recurring displacement of each ball 23 in the ball chamber 22
generates a varying torque time to time.
[0029] As shown in FIG. 1, the power generating device 4 is a
single device that operates independently and drives coils of the
power generating device 4 to generate electricity through the
rotation of the power input shaft 41. In other embodiments, the
power generating device 4 may also be a set of power generators
containing a plurality of generators that are used in parallel.
[0030] With the abovementioned structure, the kinetic assisting
device formed by the rotating disk 2 and the securing ring 3
achieves an object of a smoother rotating movement for the power
input shaft 41 of the power generating device 4 such that the wind
power generating device 100 is capable of maintaining a time period
of electricity generation even when wind speed is low or none due
to vehicle stop, and further enhances the practical requirement of
wind power generating device as being installed in a vehicle.
[0031] The above description should be considered only as an
explanation of the preferred embodiment of the present invention. A
person with ordinary skill in the art can make various
modifications to the present invention based on the scope of the
claims and the above description. However, those modifications
shall fall within the scope of the present invention.
